Piggy is a child who loves reading. He likes reading some extra-curricular books very much. Two days ago, his father bought him a math story book, 135 pages in total. He likes it
Up to now, the number of pages I haven't read is one fourth more than the number I have read. Do you know how many pages piggy has read?

If the number of pages read is x, then the number of pages not read is (x + quarter x), then the equation x + (x + quarter x) = 135 can be formulated, and the equation x = 60 can be solved

Is the speed of light meaningful to the formula of special relativity

The denominator is 0, meaningless

How to solve 4 (2x + 5) - 3x = 7 (X-5) + 4 (2x + 1)

4(2x+5)-3x=7(x-5)+4(2x+1)
8x+20-3x=7x-35+8x+4
5x+20=15x-31
15x-5x=20+31
10x=51
x=51/10

Rectangle area: rectangle perimeter: square area: square perimeter:

Rectangle area = length × width
Circumference of rectangle = (length + width) × 2
Square area = side length × side length
Square circumference = side length × 4

How to change R / min to rad / S

2 rad / S = 60 rpm

8x-30 = 3x + 20 (solving equation)

8x-3x=20+30
5x=50
x=10

A 20 cm long, 15 cm wide rectangular cardboard, cut from the four corners of the side length of 5 cm cuboid, and then made into a rectangular uncovered. How much cardboard does it use

20 × 15-5 × 5 × 4 = 200 (cm2)

The speed of an object moving in a uniform and straight line has nothing to do with the distance and time

What is the minimum value of the formula 3x & # 178; + 6x / 0.5x & # 178; + X + 1?
In order to repair a 120 meter section of the railway, the construction team repaired 5 meters more every day than originally planned. As a result, the train was opened four days ahead of schedule

There is a big gap between the two questions. One is a senior one and the other is a junior two. What grade are you in?
The first question is like this (discriminant method)
Let y = (3x & # 178; + 6x) / (0.5x & # 178; + X + 1)
The quadratic equation with X as the unknown is (Y / 2 - 3) x & # 178; + (Y - 6) x + y = 0
When y / 2 - 3 ≠ 0, the quadratic equation with one variable must have real roots,
So ⊿ ≥ 0 is (y-6) &# - 4 (Y / 2-3) y ≥ 0
The result of solution - 6 ≤ y ≤ 6
If y = 6 is taken into the original formula, there is no solution, so - 6 ≤ y < 6
Obviously, the minimum value of the original formula is - 6
Second question:
If the original plan is to build x meters per day, the actual plan is to build x + 5 meters per day
According to the original plan, 120 meters will be built in 120 / X days, but in fact 120 / (x + 5) days,
120 / X - 120 / (x + 5) = 4
If the denominator is removed, the integral equation is X & # 178; + 5x - 150 = 0
If you're a sophomore, you can't solve this equation. You can't learn it until the third grade
The factorization on the left side of the equation yields (x + 15) (x - 10) = 0
Because x cannot be negative, x = 10
A: it was originally planned to build 10 meters a day
